We've had her for 4 months and she's always been very sweet and docile, but the last week or so, she has started biting very hard when we try to hold her. She is most definately not pregnant - she lives alone in her cage. Could it be because we recently got another hamster (in a different cage, but it's right next to hers)? How can we get her to stop biting us so hard?
My winter white hamster has become aggressive?
